Title: Improvements in electrical wall plugs
IPC: H01R13/193
Filed: 1920-10-19
Abstract: 152,665. Ten Bosch, A. July 23, 1919. [Convention date]. Plug-and-socket couplings.-In a wall-plug, the contact-pins each consist of two parts which are rotatable separately or together about a stationary point or points so that the extremities of the parts may be moved towards or away from each other. The movement may be obtained automatically by a button or pin projecting from the face of the plug and engaging the face of the socket, or at will by a pin projecting from another part of the plug. As shown in Fig. 1, each contact-pin 2 is in two parts, one hinged to the other, and wedges 8 attached to the end of a bridge-piece 7 lie between the parts. The bridge-piece 7 is secured to a spring button or pin 6 which is pressed in by the face of the socket when the plug pins ara engaged with their sockets, thus pressing the extremities of the pins 2 apart. In the modification shown in Fig. 3, the pin-halves are separately pivoted in the plug 1 and have diverging inner ends encircled by rings 12 carried by the bridgepiece 7. In both forms, springs 10 engage the cuter sides of the pins. In the form shown in Fig 5, the pin-halves are hinged scissor-fashion on pivots 4 and extended into plates at their inner ends, each of which is slotted. The slots 13, 14 normally lie out of alinement, and pins 15 carried by the bridge-piece 7 engage them and by sliding therein aline the slots and so press the extremities of the pins apart. In the form shown in Fig. 7, the pin-halves are hinged at their inner ends and springs 16 lie between them, holding their extremities apart until pressed together by engagement with their sockets. The lead wires are in each case attached to one half of each contact-pin.

Abstract: 744,959. Mineral-mining apparatus. COAL INDUSTRY (PATENTS), Ltd. Oct. 26, 1953, No. 29531/53. Classes 68(1) and 85 In a mineral-mining apparatus the axis of a rotatable, pick-carrying unit 15, e.g. a drum or an assembly of axially spaced discs, of cutter unit mounted on for movement along a conveyer, is positioned horizontally to one side of and at an angle to the longitudinal axis of the conveyer, and the unit 15 is of such dimensions that the picks thereof cut down to the level of the bottom of the conveyer. Positioned behind the cutter unit is a loader 19 having surfaces 25, 26, that deflect mineral from the unit 15 into the conveyer, and surfaces 28, 27 that load mineral-onto the conveyer when the apparatus is flitted back in the direction opposite to the direction of travel when cutting occurs. The loader, which slides along the floor, may be integral with or be separate from the cutter unit and connected thereto by links and is guided by the side of the conveyer. Water is sprayed on to the unit 15 from nozzles in the surface 25 of the loader, that can be provided with a spring-loaded curved buffer between the machine and either the face or the conveyer. To prevent overturning of the cutter unit the haulage rope of the apparatus passes around pulleys 46, 47 on said unit, which may be provided with other cutter means, e.g. a cutter bar or chain - carrying jib, operating at a level above the unit 15. A bracket 33 on the loader permits of it, when not in contact with the face C, being connected to the haulage rope to prevent slewing. To allow of the use of pick-carrying units of different diameters, spacers may be inserted between the conveyer and the cutting unit or the pick-carrying unit may be carried by an arm pivotally mounted on the cutter unit for movement in a vertical plane.

Title: Improvements in or relating to apparatus for playing gramophone records
Inventor: METCALFE CLIFFORD
IPC: G11B25/04
Filed: 1949-11-22
Abstract: 689,176. Driving sound reproducing machines. ELECTRICAL & MUSICAL INDUSTRIES, Ltd. Nov. 22, 1950 [Nov. 22, 1949], No. 29803/49. Class 40 (ii). In a gramophone of the kind in which a switch bar is moved from one position to another according to whether the turntable is to be revolved at slow speed for a pick-up intended for microgroove records or at normal speed for a pick-up intended for normal records, the circuit, of the motor is not completed until the correct pick-up has been lifted from its rest, which rest incorporates a switch, normally open-circuited until the pick-up is raised. When the switch bar 23 is moved to the right, as viewed in Fig. 2, for slow speed, the contact 40, Fig. 3, of switch 36 is moved to contact 42, but circuit through the switch 20 to drive motor 43 is not completed until arm 3, carrying the pick-up for micro-groove records, is raised. Similarly, when the switch bar 23 is moved in the opposite direction for normal speed, the contact 40 of switch 36 is moved to contact 41 and circuit is not completed until arm 4, carrying the pick-up for normal records, is raised and switch 44 closed. The change of speed of the turntable is accomplished by the axial movement of a jockey pulley 13 which engages the part 11 or 12 of the motor shaft depending on the position of a ramp 35 on the bar 23. During this axial movement the jockey pulley 13 is moved against the tension of a spring 33, out of contact with the motor shaft, by means of a cam 30 on the bar 23. The switch bar 23 also operates a switch 37 whereby the connections of the pick-ups to the amplifier are changed over. Specification 667,768 is referred to.

Title: Improvements in or relating to shoe upper conforming machines
IPC: A43D21/12
Filed: 1920-10-22
Abstract: 174,431. Roberts, W. T. B., Bates, A., and British United Shoe Machinery Co., Ltd. Oct. 22, 1920. Lasting and pulling-over.-In a machine which " pulls over " under the operator eye and lasts the toe portion, the margin of the upper around the toe is held for the lasting by yielding means of the machine with a grip which, compared to that prevailing during pulling-over, is reduced and slipping. Mechanism of the type described in Specifications 7005/00 and 12304/03, having but a single pair of gripping jaws at each side of the shoe, may be used to give a transverse pull to the upper; and, preferably, a fore-draw by mechanism of the type described in Specification 13175/03. The edge of the upper around the toe is then clamped between wiper plates and a curved presser 92, Fig. 9, by the descent of a triangular plate 110 also actuating a last-depressing foot 96. The upper is thus stretched over the toe, slipping as required between the wiper plates and the presser 92. As the side pincers move inwards to lay the upper over the last a latch 120 is released, allowing a plate 108 to move upwards about its pivoted connection with the plate 110, the grip on the upper of the presser 92 being then governed by a light spring 124 in. stead of a heavy spring 106. Wiper plates then advance over the upper, and a binding-wire, previously automatically fed into a groove in their advancing edges, is secured by tacks at its ends. The groove for the binding-wire is in line with offset holes 62, Fig. 6, in one of each pair of tackholding fingers 58. The driver bar guide has a screw-thread on it engaging an adjustable screw in its casing. This guide is rotated by a flexible shaft after the tack has been driven, with the result that the wire is wound round the tack and the guide and fingers are simultaneously raised to clear the tack. Between operations on consecutive shoes, wire feeding and severing mechanism is operated to thread a fresh binding-wire through the holes in the fingers 58 and the grooves in the wiper plates. For this operation a flexible shaft drives a shaft 276, Fig. 11, first in one direction and then in the opposite. The shaft 276 carries a pinion 274, which drives a frictionally-held pinion 224 and also a pinion 236 splined to a shaft 238 screw-threaded into its bearing and having at its lower end a clutch member 242. The pinion 224 gears with a rack 226 and moves a carriage 220, on which these pinions and shafts are mounted, to and from one of the tackers. When the clutch member 242 has descended sufficiently to engage a co-operating member 244, a wire-feeding roll 256 draws wire from a reel 262 till a cam 254 separates the mem. bers 242, 244. The first opposite rotation of the shaft 276 causes a cam 272 to depress a plunger 270, oscillating a notched cutter 264 to sever the binder. Continued rotation of the shaft 276 returns the carriage 220 to normal position. Specifications 18163/09 and 18270/09 also are referred to.
